Hybrid tea rose plant name ‘Jasper Crane’

ABSTRACT

A new and distinct variety of rose plant of the hybrid tea class, characterized by its continuous production of brilliant red well-formed blooms on long straight stems, its vigorous upright habit of growth, its excellent branching, its large open flowers and its intense rose fragrance.

FIELD OF THE INVENTION

This invention relates to a new and distinct variety of rose plant of the hybrid tea rose class.

SUMMARY OF THE INVENTION

The invention is a new and distinct variety of rose plant of the hybrid tea class, which was originated by me by crossing the rose variety known as ‘Mister Lincoln’ (U.S. Plant Pat. No. 2,370) with the variety known as ‘Chrysler Imperial’ (U.S. Plant Pat. No. 1,167). As a result of this breeding, I have produced a new and improved rose variety which is distinguished from its parents, as well as from all other rose varieties of which I am aware, as evidenced by the following unique combination of characteristics which are outstanding therein:

-   -   (1) Continuous production of brilliant red well-formed blooms on         long straight stems.     -   (2) Vigorous upright habit of growth.     -   (3) Excellent branching.     -   (4) Large open flowers.     -   (5) Intense rose fragrance.

Asexual reproduction of this new variety by budding was first performed in West Grove, Chester County, Pa., U.S.A. Asexual reproduction of this new variety in West Grove, Pa., U.S.A., shows that the foregoing and all other characteristics come true to form and are established and transmitted through successful propagation.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flower of this new variety, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with a Royal Horticulture Society Colour Charts (R.H.S.C.C.), except where ordinary dictionary significance of color is indicated.
